Hello to you both I too am a Cairo, my family comes from San Marco Argentano, near Cosenza. We maybe related. My Father is Mario Cairo, his father was Guiseppe Cairo my Nonno, He was born in 1911. And my great Grandpa was Giovanni Cairo born in 1886. and my great great grandpa was born in 1853 or so.

Here is this link to a great web site that was given to me by a cousin in Calabria. Go to the word on the top that says
Cognomi then go to the letter C then find Cairo and click on it it will then open the Cairo family tree. Please take a look at it and see if anyone could fill in the blanks.
My strand of Cairo comes from Number seven. Lets see if we can connect the dots.
